What is the northern plate boundary of the Indian plate? A. The Mid-Atlantic Ridge B. The Himalayas C. The Kirthar Mountains D. The Java Trench Explanation: The Himalayas were formed by the collision of the Indian and Eurasian plates, marking the northern boundary of the Indian plate. 2 / 202. What is the “rim of fire”? A. The zone of active volcanoes around the Pacific Ocean B. The edge of a tectonic plate C. The boundary between two continents D. The area where seafloor spreading occurs Explanation: The “rim of fire” refers to the region around the Pacific Ocean with a high concentration of volcanic activity. 3 / 203. What is the slowest moving oceanic ridge? A. The East Pacific Rise B. The Arctic Ridge C. The Mid-Atlantic Ridge D. The Indian Ocean Ridge Explanation: The Arctic Ridge has the slowest rate of plate movement compared to other ridges. 4 / 204. What is the approximate age of the oldest rocks in the oceanic crust? A. 540 million years old B. 200 million years old C. 4,600 million years old D. 3,200 million years old Explanation: The age of rocks in the oceanic crust does not exceed 200 million years, significantly younger than the oldest continental rocks.5 / 205. What is a subduction zone? A. Where plates slide past each other B. Where crust is destroyed C. Where mountains are formed D. Where new crust is generated Explanation: A subduction zone is where one tectonic plate sinks beneath another, leading to the destruction of the crust. 6 / 206. What was the name of the sea that separated India from Asia? A. The Indian Ocean B. The Pacific Ocean C. The Atlantic Ocean D. The Tethys Sea Explanation: The Tethys Sea separated the Indian and Eurasian plates before their collision. 7 / 207. What major event occurred during India’s movement towards Asia? A. Formation of the Atlantic Ocean B. Formation of the Mariana Trench C. Outpouring of lava and formation of the Deccan Traps D. Separation of Australia from Antarctica Explanation: The Deccan Traps were formed by massive volcanic eruptions during India’s northward movement. 8 / 208. What type of plate boundary is the San Andreas Fault? A. Transform boundary B. Subduction zone C. Convergent boundary D. Divergent boundary Explanation: The San Andreas Fault is a transform boundary where plates slide horizontally past each other. 9 / 209. When did India collide with Asia? A. 200 million years ago B. 100 million years ago C. 10 million years ago D. 40-50 million years ago Explanation: The collision of India and Asia, leading to the formation of the Himalayas, occurred around 40-50 million years ago. 10 / 2010. What happens to the oceanic crust at deep trenches? A. It remains unchanged B. It is destroyed C. It becomes thicker D. It is created Explanation: The oceanic crust sinks and is consumed at deep trenches, balancing the creation of new crust at mid-oceanic ridges. 11 / 2011. What is the concept of seafloor spreading? A. New oceanic crust is formed at mid-oceanic ridges and spreads outwards B. Formation of mountains due to volcanic activity C. Movement of continents due to tidal forces D. Continents are stationary, and only the ocean floor moves Explanation: Seafloor spreading proposes that volcanic activity at mid-oceanic ridges creates new crust, pushing the older crust outwards. 12 / 2012. How are the rates of plate movement determined? A. By measuring the depth of trenches B. By analyzing magnetic stripes in the ocean floor C. By observing volcanic activity D. By measuring the height of mountains Explanation: The magnetic stripes in the ocean floor provide a record of plate movement, allowing scientists to determine the rates. 13 / 2013. What is the fastest moving oceanic ridge? A. The East Pacific Rise B. The Indian Ocean Ridge C. The Mid Sources and related content-Atlantic Ridge D. The Arctic Ridge Explanation: The East Pacific Rise has the fastest rate of plate movement, with rates exceeding 15 cm per year. 14 / 2014. Where was the Indian subcontinent located about 140 million years ago? A. Near the equator B. 50°N latitude C. 50°S latitude D. Near the South Pole Explanation: The Indian subcontinent was located much further south 140 million years ago. 15 / 2015. What is an example of a divergent plate boundary? A. The San Andreas Fault B. The Mariana Trench C. The Mid-Atlantic Ridge D. The Himalayas Explanation: The Mid-Atlantic Ridge is a divergent boundary where the American plates are moving away from the Eurasian and African plates. 16 / 2016. What does the term “Pangaea” mean? A. Supercontinent B. All water C. All earth D. Land of the dinosaurs Explanation: The term “Pangaea” translates to “all earth,” referring to the supercontinent that Wegener proposed. 17 / 2017. What is a tectonic plate? A. A deep trench in the ocean floor B. A type of volcano C. A massive, irregularly-shaped slab of solid rock D. A large island formed from volcanic activity Explanation: A tectonic plate, also called a lithospheric plate, is a massive slab of solid rock that makes up the Earth’s lithosphere. 18 / 2018. How many major tectonic plates are there? A. Seven B. Six C. Five D. Eight Explanation: The Earth’s lithosphere is divided into seven major and some minor tectonic plates. 19 / 2019. What is the driving force behind plate movement? A. Tidal forces B. Volcanic activity C. Convectional currents in the mantle D. Magnetic forces Explanation: The heat within the mantle creates convectional currents, which are the driving force behind plate movement. 20 / 2020. What is the asthenosphere? A. The mobile layer beneath the lithosphere B. The rigid outer layer of the Earth C. The solid core of the Earth D. A type of tectonic plate Explanation: The asthenosphere is the partially molten layer beneath the lithosphere, over which the tectonic plates move.
